I fully understand that SharePoint 2016 DBs must be on SQL SERVER 2016+. My question is NOT related to SharePoint databases (DBs SharePoint uses to manage the site).
However, my environment has many 2008R2 databases. SSRS reports run independently through Report Server (2008 Report Server). However, we also have SharePoint2010 (through Excel services) grabbing data from both SQL Server 2008R2 DBs as well as SSAS (2008). What is the compatibility of those with SQL Server 2008R2?
Could Excel Services (Office Online) access SQL 2008? Are there any documentation on these compatibilities? Because I was unable to find anything.
